There are several reasons why your dog is itching his eye. When you notice your dog itching their eye excessively, you will need to examine the affected eye for any visible foreign object. You can flush the eye with warm water or a sterile saline solution. If flushing the eye does not remove the irritant, you will need to make an immediate appointment with your veterinarian. When it comes to eye care, it is essential that you have your veterinarian assess your dog and provide appropriate treatment.
In-Grown Eyelids
In-grown eyelids can be a hereditary problem or they can be the result of continuous inflammation. The eyelids will turn inside and the eyelashes press against the eye. When your dog itches or rubs at the affected eye, they can create a large ulcer.
Inflammation From Infection
When you notice the area around the eye or even the eye itself is inflamed, that is generally a sign of an infection in the eye. Your veterinarian will prescribe eye drops and may even prescribe oral antibiotics.
Irritation and Allergies
Dry eye, dirt, pollen or other small foreign particles can invade your dog’s eyes. These foreign particles can cause scratches on the cornea and intense irritation. You can flush your dog’s eye with a sterile saline solution. If the eye is still irritated after flushing it be sure to contact your veterinarian and have it checked.
Prolapse of the Third Eyelid
Your dog has a third eyelid that protects the cornea and the gland within the third eyelid produces tears to provide lubrication for the cornea. The gland will sometimes become swollen and then bulge up and over the top of the third eyelid. This can cause irritation and will produce yellow mucus.
Corneal Ulcer
This will occur when your dog experiences a more severe eye injury, usually from a foreign object such as a cat’s claw, thorn or twig. Your veterinarian will need to assess your dog’s corneal ulcer and determine the best course of action. Most dogs make a full recovery from a corneal ulcer.
Pink Eye
Dog pink eye, also known as dog conjunctivitis, will affect your dog the same as pink eye affects humans. Your veterinarian will be able to diagnose dog pink eye quickly based on the symptoms and begin treatments immediately.
